Abstract:
An audio control system of a vehicle includes a sound control module configured to determine N magnitudes for outputting a predetermined engine sound at N frequencies, respectively, where N is an integer greater than one. A magnitude adjustment module is configured to determine at least one N magnitude adjustment values for the N frequencies, respectively, based on at least one of: an intake air temperature; and an exhaust temperature. The sound control module is further configured to determine N adjusted magnitudes for the predetermined engine sound at the N frequencies based on: the N magnitudes for the N frequencies, respectively; and the N magnitude adjustment values for the N frequencies, respectively. An audio driver module is configured to apply power to at least one speaker of the vehicle and output the predetermined engine sound at the N frequencies and the N adjusted magnitudes for the N frequencies, respectively.
